Prologue: Hiro's Transformation

[The film opens to Thomas and his friends chuffing through the hall of the Castle of the Royal Pony Sisters. In the throne room, Princess Luna stands in front of Hiro in his pony form with a ball of black nebula smoke behind her]

Princess Luna: [lifts her head and opens her eyes] Are you ready, Hiro?

Hiro: [lifts his head and opens his eyes] Yes. I'm ready, Luna.

Princess Luna: Then let us begin. [moves away so that Hiro now stands beneath the ball of nebula smoke]

Thomas: [arrives with his friends] Hiro, wait! You don't have to do this!

Hiro: I have to, Thomas. I must.

Princess Luna: The time has come for Hiro to face the true fears that nightmares bring.

[An eclipse happens and Hiro is englufed in a dark ball of magic. It then turns orange and Hiro bursts out, now wearing blue armor like Nightmare Moon, only he now wears a helmet. His pupils turn into slits and he grows fangs as he laughs evilly]

Optimus Prime: I am very disappointed in you, Thomas. You never were able to protect the Blue Ruby, Black Pearl and Matrix of Leadership safe from Tirek. You weren't able to stop Unicron from invading Cybertron. And you were never able to stop the Decepticons from ruling Earth. I never should've chosen you to be a Prime.

Ryan F-Freeman: I think I waited long enough.[throws his Keyblade at Optimus which impales him] You are dead!
